The role

DualEntry is building the OS for finance.

Every business needs a financial system of record, yet the world's largest fintech market ($220B+) still runs on software from the 1990s. DualEntry's AI-native ERP automates accounting from data entry to close, so finance teams move faster, spend less and incur less risk.

In just 2 years we've raised $100M+ from Lightspeed, Khosla Ventures, Contrary and Google Ventures and earned the trust of customers from $5M ARR to publicly traded companies.

We hire outliers - people who have achieved difficult things, in their careers or beyond. You'll find leaders, colleagues who've competed at the highest levels of sport, performed on Broadway, trained with UFC champions and founded the country's largest Python community.

What you'll do

Build!
Design backend systems and APIs (Python preferred) that run real-time, business-critical accounting logic
Ship features end to end - architecture, CI/CD, testing, monitoring, and beyond
Integrate third-party tools and external systems, proactively managing edge cases and risk

How You Operate

Pragmatic: you like to move forward and make decisions based in reality (not theory). We don't debate if Cassandra has the most theoretical scalability - we use Postgres until it breaks
Hard working: 'You can work long, hard, or smart, but [here] you can't choose two out of three' - Jeff Bezos.
Curious: you love to learn, are highly curious about new frameworks and solutions to engineering problems
Fast-moving: you deploy daily, iterate quickly, and never wait for permission
